KITCHEN-RANGE.

Specification of Letters Patent.

Patented Mar. f6, 1915.

Application filed June 8, 1912. Serial No. 702,384.

To all whom it may concern:

Be it known that 1, JOHN ERBnN, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Kitchen-Ranges, of which the following is a specification.

My invention relates to an improvement in kitchen ranges, and the invention consists more particularly in means for utilizing either natural or manufactured gas in a range which otherwise is adapted to be used with solid fuel without gas. This constitutes a convertible range having the features of construction and combination of parts, substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of the range with the parts in position to use natural gas, and Fig. 2 is a similar view with the parts in position to use artificial gas. Fig. 3 is an enlarged sectional elevation of a portion of the range showing the burners positioned to use natural gas, and Fig. 4: is a corresponding view showing the burners arranged to use artificial gas. Fig. 5 is a front elevation of a regulating plate seen in elevation also in Figs. 1 and 2 and adapted to make the desired change according to the gas used and the air desired as hereinafter more fully described. Fig. 6 is a plan view of the range with the top plate removed and disclosing the gas burners beneath, and Fi 7 is a per spective view of an angle-bar adapted to support the burner pipes in different elevations according as natural or artificial gas is used.

The range as thus shown is provided with a grateto burn wood or coal, but is eonvertible to use either manufactured or natural gas as conditions may require. For example, the range when used with solid fuel is provided with the usual fire pot and two dampers cl and cl adapting the same to be converted to use gas as above indicated. When gas is used both dampers (Z and d are closed and gas burners b are placed in the space immediately over or upon the said dampers beneath the top of the stove. The said dampers (Z and d control the flow of the products of combustion which pass around the oven, not shown, and have their exit over the top of the stove into the chim ney. However, I provide a removable walled inclosure indicated by 0 in this space which has a bottom resting upon the said dampers and side walls so as to practically make a burner chamber in the said space and exclude air from either bottom or side. The burners Z) are placed in this chamber or space and adapted to rest upon the said bottom 0 directly or indirectly as shown in Figs. 3 and 4, according to the gas that is used.

Natural gas, which generally has a lower pressure than the manufactured gas and very often is uncertain in its pressure, requires that the burners be raised to a higher elevation than for manufactured gas, and to this end each burner is provided with a differential projection 2 on its bottom having two diameters, and a rotatable support or plate 3, Fig. 6, is pivoted on the bottom plate 0 and adapted to swing under the said pro ection 2 and has a hole corresponding to the smaller diameter or point of said pro- ]ection and in which the projection rests when the burner is raised as in Fig. 3. When the burner is to be changed for manufactured gas the said support or plate is swung to one side and the larger diameter of the pro ection 2 comes into the corresponding hole in the bottom 0 and rests the burner down upon said bottom. The two parts shown in Figs. 5 and 7 respectively, are likewise adapted to these changes, and the plate D, Fig. 5, has a series of air openings a and a parallel series of tubular openings 5, and the burner pipes 6 are projected through sai tubular openings while the air openings are free for the admission of air into the burner chamber. A damper 8 has holes corresponding to the holes 4% and pipes 6 and it serves to close all said openings when the pipes (5 are removed and the range may use solid fuel. Small brackets 9 with screws or bolts 10 are adapted to support the plate D on the range and can be released when the said plate is to be inverted to bring the holes beneath, as in Fig. 1 and as occurs when natural gas is used. The right angled support or bar B, Fig. 7, is provided with a series of recesses 12 and 14:, respectively, at different depths in its upper edge according as the burners with their pipes 6 occupy the higher or the lower elevations of the range, and the said bar serves as a support for the said pipe in either case. The notches or re cesses 12 correspond to the higher position of the burners and the notches or recesses 14 to the lower positions thereof, Fig. 4. Said bar also has slots 15 in its ends and bottom adapted to be secured by bolts to the bottom 0 of the chamber and adjustable lengthwise more or less therein to adapt it to the position of the burners and their supply pipes 6. When solid fuel is used the wall 0 of the burner chamber and the burners are removed and then the range is restored to its original condition.

What I claim is:

1. A convertible range having a burner chamber provided with holes in its bottom, in combination with burners in said chamher having projections adapted to enter said holes, and means adapted to engage said projections and hold said burners in a raised position in respect to said holes.

2. A kitchen range having gas burners removably supported in the top thereof, devices to sunnort'said burners at dii'i'erent elevations according to the kind of gas used and an invertible plate at the front of the range having a series of air inlet holes and Copies of this patent may be obtained for a separate series of openings adapted to re ceive the pipes leading to said burners.

A kitchen range and gas burners in the top thereof, means to support said burners at different elevations according to the kind of gas used, burner pipes and a support therefor having notches of varying depths to support said pipes according to the elevations of said burners and a reversible air inlet plate having a series of holes for the admission of air to said burners and another series of holes for the burner pipes.

4. A convertible range having gas burners in its top provided with differential projec tions on their bottoms, in combination with a bar to support said burner pipes having recesses of varying depth in its top and adjustable lengthwise to bring recesses of different elevation into working position.

In testimony whereof I afiiX my signature in presence of two witnesses.

JOHN ERBEN.
